Abstract

The invention discloses a transverse magnetic flux multi-phase reluctance motor, and relates to a reluctance motor, which solves the problem that magnetic coupling is existed between phases in a traditional multi-phase permanent magnet synchronous motor to affect the control precision of current. The reluctance motor consists of a stator and a rotor, wherein m phase armature units are arranged inan enclosure along an axial direction in sequence, and each phase armature unit is staggered in a 360 DEG / m electrical angle along a circumference direction in sequence; an armature coil is embedded in an annular space formed among first to third circular iron core sections; permanent magnets are fixedly arranged on the internal surfaces of the first and the third circular iron core sections along the circumference direction with alternated N-pole and S-pole in sequence; and a pole distance taum between every adjacent two permanent magnets and a tooth space taup of rotor teeth arranged along the circumference direction satisfy the formula of 2taum=taup. The reluctance motor disclosed by the invention eliminates the alternating mutual inductance, improves control accuracies of motor current and electromagnetic torque and dynamic property of ta system; and improves the reliability and the safety of the motor since the permanent magnets are located above the stator.

Description

technical field [0001] The invention relates to a reluctance motor, in particular to a multi-phase reluctance motor. Background technique [0002] The structure of the traditional multi-phase permanent magnet synchronous motor, such as figure 1 As shown; the armature winding of the motor is a distributed winding, the number of coils required to form the winding is large, the winding ends of each phase of the winding cross each other, the winding ends are long, and the copper consumption is large; the winding insulation is complicated and the manufacturing cost is high. Since there is magnetic coupling between phases, on the one hand, the existence of mutual inductance will affect the control accuracy of the current; The power consumption is large, which limits the further improvement of the motor efficiency. At the same time, since the permanent magnet is located on the rotor, the structural strength and allowable temperature rise of the rotor are limited, which restricts ...
